It also depends a lot on your road surface. On grippy asphalt, I can hardly get a chirp from my P85 tires even w/ TC-Off. In a concrete-surfaced parking garage, or on a drag-strip's concrete burnout lane, i can easily leave 50-ft long rubber-marks, spin the tires to shreds, & squirrel sideways all-over, w/TC-Off.
Try an unused level of a concrete parking garage w/ TC-Off, and I'll be astonished if you can't scare yourself with the burnout and hooligans. If you can't approach this, then yeah, you should check w/ your SC re available power.
On a slick concrete surface, a P85 w/ TC-Off should truly scare the **** out of you wrt to wheel-spin..
